Kongregate is a Web2.0-like game site, so let's just say it's Games2.0. Haven't quite given it a full test ride, but I have good confidence in this site. It just feels right, as this screencap shows:
Kongregate is great for gamers.
By wrapping user-submitted Flash games with various community features, Kongregate's site serves as a unique way for users to play great web-based games alongside friends.
And Kongregate is also great for developers.
Kongregate operates with an understanding of how difficult it can be for talented game developers - from the aspiring gamesmith to the independent studio - to get the recognition and compensation that they deserve. That's why Kongregate shares microtransaction and advertising revenue with contributing developers, who retain the full rights to their games.
